Zorlu, Barkın (2018) Which method is more effective in determining the amount of Pb2+ ions in mole found in water; precipitating Pb2+ ions in water sample as PbS (L1ead(II) Sulfide)by using Na2S (Sodium Sulfide) or by titrating the excess EDTA with ZnSO4 (Zinc Sulfate) solution when EDTA is added to the water sample containing Pb2+ ions?

Abstract
In this study the aim was to determine which way of determining lead dissolved in water is the most efficient way to use. As I am involved with heavy metals as my hobby requires it to be I am interested in how much lead there really is in water and for this I needed an efficient way. My teacher and I decided on using two methods which are, Gravimetric Method and Complexometric Back Titration Method. The reason why Gravimetric Method was selected was that it could be used in nature and is an effective way of neutralizing lead dissolved in water and the reason why Complexometric Back Titration Method was selected is because EDTA is used for Chelation therapy, a method that is used to remove too much lead in blood flow of a living being. With these two methods, we have two ways of determining lead dissolved in water, and each method are useful for two parts of our lives Gravimetric Method the nature and Complexometric Back Titration Method for human health which are really important as it addresses more than one Topic in this case: Nature and human health. As a result of the experiment I found out that Gravimetric Method is far more efficient than Complexometric Back Titration Method. Gravimetric Method is simpler and shorter than Complexometric back Titration Method thus, less error to occur during making of the experiments.
